\fb. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? There appears to be a - Select your answer - |linear relationship between x and y. c. Try to approximate the relationship between @ and y by drawing a straight line through the data. Select your answer - to provide a linear approximation of the relationship between a and y. d. Develop the estimated regression equation by computing the values of bo and b1 using equations: (Enter negative values as negative figure) E(x; - )(yi - y) b = bo = y - bid 1 = + (to 2 decimals) e. Use the estimated regression equation to predict the value of y when = = 13. y = (to 2 decimals)
